Types of Philosophical Problems in Wittgenstein's Philosophy

Seven different types of philosophical problems can be found in the texts of late Wittgenstein, says the authoress. She offers this differentiation in order to support the claim that Wittgenstein was not working under a clear assumption that philosophy had a well defined scope. It amounted to much more for him that simply an attempt to make sense of a difficulty that caused confusion in the mind, as he himself argued. Type (1): problems arising from grammatical similarity of the kind to which some expressions belong; Type (2): problems causes by illegitimate attempt to attain some sort of an ideal; Type (3): problems caused by unconscious confusion of incompatible language games; Type (4): problems created by undermining the rules of ordinary language; Type (5): problems that are occasioned by an illusion created by a picture; Type (6): problems that are caused by treating philosophy as if it were science; Type (7): problems generated by efforts to attain philosophical depth.
